The method includes the following steps. Firstly, the at least one computer downloads and executes a test application program. Then, the at least one computer is connected to the first server, and provides a device identification code and a network address value of the at least one computer to the first server. If the first server judges that the corresponding device identification code complies with a first default condition and the corresponding network address value complies with a second default condition, the corresponding computer is authenticated, and a test setting information is provided from the first server to the corresponding computer.

Abstract: An electronic scale calibrating method for an electronic scale is provided. The electronic scale includes a weighing pan, a memory unit, a first weight sensor and a second weight sensor. The weighing pan has a placement region. The first weight sensor and the second weight sensor are symmetric with respect to the placement region. Firstly, two standard samples are placed in the placement region simultaneously. Then, the first weight sensor and the second weight sensor sense the two standard samples to obtain a first read value and a second read value, respectively. Then, a first parameter, a second parameter, a first calibration coefficient and a second calibration coefficient are defined according to the first read value and the second read value. Then, a calibration formula is generated and stored in the memory unit.

Abstract: A camera module testing method is applied to a camera module including a camera lens and a photosensitive element. In a step (A), an original image is captured through the camera lens and the photosensitive element. In a step (B), the original image is converted into a gray scale image. In a step (C), the gray scale image is converted into a binary image according to a critical gray scale value. In a step (D), a boundary contour is obtained according to plural pixels of the binary image higher than or equal to the critical gray scale value. In a step (E), a contour center of the boundary contour is obtained. Then, a step (F) is performed to judge whether an optical axis of the camera lens is aligned with an imaging center of the photosensitive element according to the imaging center and the contour center.

Abstract: A sensor testing system includes a standard unit and a test fixture. The standard unit and plural under-test sensors are placed on a test platform of the test fixture. A sensor testing method includes following steps. Firstly, the standard unit and the plural under-test sensors are arranged to generate a main process. Then, the standard unit and the plural under-test sensors are assigned to generate plural sub-threads according to the main process. When the main process is executed, the plural sub-threads are synchronously executed. Then, the test platform is enabled to create a motion in a first direction, and the main process waits for a predetermined time period. Then, the standard unit and the under-test sensors sense the motion in the first direction. When the sensing results are generated, the standard unit and the under-test sensors respond to the main process.

Abstract: A luminance adjusting method for a display screen of an electronic device includes the following steps. Firstly, a current brightness value and a current imaging color value of the display screen are recorded. In response to the user's operation, the light output of the display screen is adjusted. Consequently, the adjusted brightness value is equal to a default brightness value and the adjusted imaging color value is equal to a default imaging color value. Meanwhile, the display screen is operated in the healthy display mode. In response to the user's additional operation, the light output of the display screen is adjusted. Consequently, the adjusted brightness value is equal to the recorded current brightness value and the adjusted imaging color value is equal to the recorded current imaging color value. Meanwhile, the display screen is restored to the normal display mode.

Abstract: A membrane switch circuit testing system includes a testing module and a connection element. After the connection element is connected with a membrane switch circuit and the testing module, the testing module assigns an identification code to a key intersection of the membrane switch circuit. When the key intersection is depressed, an equivalent circuit is defined by the depressed key intersection and a corresponding fixed resistor of the testing module. Moreover, the testing module acquires an intersection resistance value of the depressed key intersection from the equivalent circuit. Consequently, the testing module judges whether the depressed key intersection is qualified according to the intersection resistance value.
